See a solution process below:

Explanation:

The formula for calculating the percent change in a value between two points in time is:

#p = (N - O)/O * 100#

Where:

#p# is the percent change - what we are solving for in this problem.

#N# is the New Value - 98 in this problem.

#O# is the Old Value - 70 in this problem.

Substituting and solving for #p# gives:

#p = (98 - 70)/70 * 100#

#p = 28/70 * 100#

#p = 2800/70#

#p = 40#

There is a 40% increase from 70 to 98
